general taxon notes:
There are about 70 species of Neckera in the world, and about half of them are well understood (Crosby et al. 2000). Seventeen species are treated here for China. Recently, N. enrothiana M.-C. Ji (M.-C. Ji & L.-H. Miao 2009) and N. xizangensis Enroth & M.-C. Ji (Enroth & M.-C. Ji 2010) were described from Sichuan and Xizang, respectively. I did not study the types. From the illustrations and descriptions, N. enrothiana appears to be very similar to N. borealis Nog. and N. xizangensis is close to what I consider to be N. pennata Hedw. in Bryoflora of Xizang (X.-J. Li 1985). Neckera bhutanensis Nog., N. denigricans Enroth, and N. pusilla Mitt. were recently reported from China by M.-C. Ji and Enroth (2010), but no specimens have been seen. The following species reported sporadically from China (Redfearn et al. 1996) cannot be verified: Neckera coreana Cardot, N. crispa Hedw., N. douglasii Hook., N. fauriei Cardot, N. leptodontea Müll. Hal., and N. pennata var. leiophylla Dixon.

5. Neckera Hedw.   平藓属   ping xian shu
Sp. Musc. Frond. 200. 1801.
Neckeradelphus Laz., Bot. Žurn. (Kiev) 2(1): 86. 1941.
 
Plants usually medium-sized, sometimes small or rather large, yellowish green when young, brownish green when old, often glossy, in loose or flattened mats. Primary stems creeping, mostly with brownish rhizoids; secondary stems ascending or pendulous, complanately foliate, simple below, unipinnately or rarely 2–3-pinnately branched above; oval or rounded in cross section, a central strand absent; branches obtuse or slenderly attenuate at the apex, sometimes with flagelliform branches. Leaves arranged in 8 rows, often complanately and obliquely appressed on stems, broadly ovate, lingulate, oblong-lingulate, or ovate-lingulate, sometimes undulate or irregularly undulate, acuminate, acute, narrowly obtuse, or rounded-obtuse at the apex; margins serrulate to serrate above, entire below, often incurved on one side at the base; costae single, reaching above mid-leaf or longer, rarely double, weak, or absent; leaf cells smooth, apical and upper cells oval, rounded-quadrate, or rhombic to shortly rhomboidal; median cells elongate; basal cells more elongate to linear, thick-walled, porose; alar cells sometimes differentiated, quadrate to shortly rectangular. Autoicous or dioicous. Perichaetia mostly on secondary stems; inner perichaetial leaves sheathing at the base. Setae short to elongate; capsules immersed to long exserted, ovoid to cylindrical; opercula conic at the base, often obliquely rostrate; annuli sometimes well developed; peristome double; exostome teeth lanceolate, light yellow, smooth or finely papillose, sometimes striolate at the base; endostome segments usually filiform or linear, sometimes reduced; basal membrane low; cilia often absent. Calyptrae cucullate, sometimes hairy. Spores spherical, finely papillose.
